CHASSIS TESTINGMack has plenty riding on our Cornerstone chassis. Components were tested for fatigue; the rails and crossmembers were stressed and relentlessly checked for endurance.

FRAME RAIL CROSSMEMBERS

WHEEL CUTSThe best All Wheel Drive truck maneuverability ever from Mack. The Cornerstone chassis design allows increased wheel cuts for improved handling around the jobsite.

ENGINE MOUNTS/ CAB ISOLATORSNew engine mounts and cab isolators reduce noise and vibration — decreasing driver fatigue and improving productivity.

The 300 mm constant frame rail height and high strength steel alloy in conjunction with a full length channel liner provide for optimal strength and payload capabilities. The frame system includes a full channel liner in each rail that runs front to rear within the Mack Defense M917A3 Heavy Dump Truck. This provides for optimal strength and payload capabilities.

Developed by Mack design engineers and harshly tested by perfomance engineers – superior strength and stiffness is achieve through the use of eight crossmembers located along the frame rails where loads are imposed.

APPLICATIONSOffers military users the capability of transporting supplies on logistic and tactical missions.

ADDITIONAL APPLICATIONS COULD INCLUDE – RADAR, TROOP CARRIER, WRECKER, TANKER, HEAVY EQUIPMENT TRANSPORT, AND OTHERS VEHICLES

The Cornerstone ChassisThis truck chassis off road superiority gives it the flexibility to transform into multiple mission capable platforms with proven success. The adaptability provides the military a diverse portfolio of tactical and logistical support equipment. The chassis is built strong (rock-solid) and when combined with a crane can offer an all-terrain solution capable of 30 to 60 tons. Making it the perfect tool for light, medium, and heavy lifts.
